ComplianceCompliance with FCC/Canada Radio Frequency InterferenceRegulationsDetermining FCC ClassThe Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCCplaces digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)or Class B (for use in residential or commercial locations). All National Instruments (NI) products are FCC Class A products.Depending on where it is operated, this Class A product could be subject to restrictions in the FCC rules. (In Canada, theDepartment of Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.) Digitalelectronics emit weak signals during normal operation that can affect radio, television, or other wireless products.All Class A products display a simple warning statement of one paragraph in length regarding interference and undesiredoperation. The FCC rules have restrictions regarding the locations where FCC Class A products can be operated.Consult the FCC Web site at www.fcc.gov for more information.FCC/DOC WarningsThis equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the instructionsin this manual and the CE marking Declaration of Conformity*, may cause interference to radio and television reception.Classification requirements are the same for the Federal Communications Commission (FCC) and the Canadian Departmentof Communications (DOC).Changes or modifications not expressly approved by NI could void the user’s authority to operate the equipment under theFCC Rules.Class AFederal Communications CommissionThis equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCCRules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operatedin a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed andused in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of thisequipment in a residential area is likely to cause harmful interference in which case the user is required to correct the interferenceat their own expense.Canadian Department of CommunicationsThis Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.Compliance with EU DirectivesUsers in the European Union (EU) should refer to the Declaration of Conformity (DoC) for information* pertaining to theCE marking.
